Not sure about that Map, but there is a kid here in N. Texas. I think he's about 16, maybe 17 now, that blows JM, and many others, away. I first heard/saw him when he was 14-15. Not only did he have the technical ability down, he had the soul of the music, the timing, etc. Sometimes it's what you don't play that matters.
His name is Tyler Dow Bryant. He's won the Robert Johnson blues award.
I've got a picture of me with him, plus an autographed CD.
Check him out......
